„In school systems with hierarchical tracks, as they are common in some European countries (e.g., Germany, Luxembourg, Switzerland, Austria), but also in Korea, China, Brazil, Russia, and Japan, tracking does take place at the school level. In these school systems, students are allocated by teachers to different schools with different curricula and different final degrees on the basis of their achievements and interests in primary school.“
